  • Resolved smallhearyou



    Thank you for your brilliant security plugin, I use it on my 2 sites, but one chinese site encounter a WordPress network error problem, so I checked the diagnose log, and it shows:

    [Scanner] ERROR: WordPress integrity data not found. Version: 5.0.3, locale: zh_TW

    Then I tried to re-install wordpress through the update page and scanned again, the error still shows up.

    Do you know how to solve this problem?

    Thank you ~

    You get this error simply because there is no integrity data for WP 5.0.3 with the zh_TW locale on yet. Probably updating to WordPress 5.1 will solve this issue.

    OK, I got it, I will try it, thank you for your suggestion.

    I found it still didn’t work after I updating to 5.1, but when I switch the site language setting to “English” then the WordPress integrity can be verified. So this problem is solved.

    One more question, I found the scan can go outside of the website folder to phpredis folder, like the absolute path: /tmp/phpredis-4.2.0/…. and shows some Suspicious code found.

    Is this normal ? Thanks.

    Cerber scans one level up only, just because on some web servers it’s possible to have infected files there. Having executable code there, other than wp-config.php, is not normal. A website has to reside in its own, separate folder that is not shared with other websites and parts of a web server. I would recommend deleting all suspicious files.

    I had this problem yesterday with verifying WP files and WP-Cerber. WP 5.1, every plugin and theme up-to-date. Every zip file I offered to “resolve issue” failed, however, despite that, they were verified in subsequent quick scans. One by one, they verified, except for WP-Cerber and WP itself. Finally, I did a full scan, and this time, WP and WP-Cerber verified! WP files get that network error (apparently) until WP-Cerber is verified, or at least it appeared so in my adventures yesterday. Your mileage, of course, may vary.

    @suzyloonam Your problem clearly tells that there are some network issues on your web server, so the scanner is unable to load checksums from Possibly the web server has a low bandwidth network connection. Ask your hosting provider for assistance or, if that happens again, I would recommend moving to a hosting provider with more powerful network uplink.

    I just moved all my sites to a VPN in December. Maybe by next December, I will have recovered enough to think about moving again.

    I raised the upload limit in wp-config, and then I scanned, over and over again, short and full scans, flipped back and forth from legacy to standard, ignored some flagged files and eventually, WP verified.

    I guess it could be my server, but it was playing kind of arbitrarily with WP-Cerber settings that seems to have made it work.

    Thanks for your reply, and for your plugin. I prefer it to all others.
